Final Product

Problem fixed and run quite well. Let's take a look how Noise Pollution Index is made. But I still found that some components cannot be well plugged like the microphone and so on. The data are not well-received (i.e. by chance! XD)

Finally done! But still needa fix it!

Finally, Noise Pollution Index was a wrap on 23/4 and presented. But there is still some problems of the use of the amplifing sound circuit because it doesn't work! I need to try again on fixing the complicated circuit or simply just use the external power (i.e. not powered by Arduino) with or without the amplifiing circuit.

Let's see the presentation LIVE!

Something get stuck!!!!

Oh my god! There is something get stuck when I try to fix the problem of storing the sound files. I found that it is out of my ability to do it (either using a breakout board with microSD card player or using a recording board). So, I have decided to change my project which is simplier and more interesting. Let's take a look at my proposal.

Arduino!!! and Some Electronic Apps

From the past experience heard from the senior classmates that they have to buy Arduino overseas, like buying from Tao Bao or Sparksfun. It may take some time to wait for the shipping. But now you don't need to wait as you can buy it in Hong Kong now. I have found this when I was searching where can I buy Arduino and related stuffs in Hong Kong. Also, the price is quite OK (HKD$138 around). So, please take a look at the following website:

In addition, I am fond of iPod Touch and it always helps me to do my work. I have found some apps that had helped me a lot during the development of my final project process and producing the final project.

1. [Getting Started with Arduino] (US $4.99) (eBook of Getting Started with Arduino)
2. [Electrical Ref] (US $0.99) (an app helping you on knowing the electronic components and some useful circuits and calculation tools provided)
3. [Electronics Toolkit] (Free) (an app providing calculation tools for 555 timer and LEDs)
4. [Electrical Toolkit] (Free) (an app providing various essential electric formula calculations)
